VENTILATORJ FOR BUILDINGS.

.m ay-.e'ioh'cer'n c v Be it known that We, THOMAS E. VAUGHN and JOHN Hi BRUNiNGA, citizens of' the `United .Statestand.residing at ,Chicago and buildings, chimneys,'and the like, andmore particularly to ventilatrs of the ejector ivre onepf uit" Obje'csof aus invention is to provide a ventilator which notv only forms an outlet v`opening;` forl the air from a building or the like, but4 which is so constructed that outside airv currents striking the same will produce by an induced action a strong' exhaust lof the airA fromv .the interior offtliebuilding.

Another Objectis to provide a ventilator ivliicli will be Asimple in construction', cheap ,to manufacture'. Will require a minimum oi" seams,f and which is so arranged that one part vivillv be nested Within the other so i that tlieivliolewill `l'forrn a strong and rigid construction; y

plain cone or casing 1 4 is mounted upon the intermediate member and is secured thereto by rivetsI extending through the.

cone and through the outer folds 12. The

intermediate member forms with the educ-L tion pipe and cone 14 a series of vertical induction passages open at the lower end and discharging at the upper end inside of the cone 14. The upper end of the intermediate member extends substantially Hush with 'l the upper end of theeduction pipe, 4and the educt'ion pipe is cut away at land opposite the outer folds 12 las shown -in the drawing. The intermediate member eX- tends a short distance belowthe cone 111, and the extension of the inner 'foldslf is greater than that o1 the outer folds 12. This construction provides deiectingr sui' faces for defecting the outside cross. currents upwardly. Y,

A cone-shaped cap 1G is supported upon the cone 14 by means of straps 1T riveted to the cap and to the cone. The insidebf the cap has riveted thereto a downwardly extending-conical member lf3, and the out- .the air from the eduction pipe and from the passage passes upwardly, it lWill strilretlie conical member 18 and will be deieeted outwardly so as to pass out through the space between the cone 14 and the cap 16. The conical member 18 will thus deflect fthe exhausted` air outwardly and out of the ventilator, causing a 4smooth exhaust action and preventing' the formation or'leddy cur.

rents which would be caused itthe member 18 was absent. The area of tlie'outlet space between the cap 16 and the cone lelie as great ora little greater than the area of the outlet of the cone 14, but the cap is placed close enough to the upper end of the cone 14 so that the outside cross currentswill not blow down the ventilator. The bottom of the cone vis also placed low enough, and the diameter of the outside rim lo'w enough is' made large enough and extends` down so that the rain cannot enter the Ventilator directly and so that the wind will not blow in the water which drips down from the edge of the cap.

Figs. 5 and 6 illustrate another form of i cut away in this case as in the' other construction, but its upper end stops a short distance below the upper end of the intermediate member. The lower inner en'ds of the folds extend some distance below" the lower ends of the outer folds as in the construction shown, in Figs. 1 to 4 inclusive, and the outer folds also extend a short distance below the lower end of the outer cone. Thecone 24 provided with the inner conical member 25 is mounted upon the .body of the ventilator b means of strapsv 26, but the rivets exten ing through the strap pass in this case through both the intermediate member and the cone 23. 'The operation of this device is substantially the same as that described in Figs. l to 4 inclusive. Due to the angularconstruction, the intermediate member can be formed easier than that .shown in Figs. l to 4 inclusive, and the parts will be more iirmly nested when assembled.

The lobes where they engage the casingv and the pipe extend for some distance circumferentially therealong. This will cause the spans between the lobes to be decreased, and'also results in a better and more uniform distributionof the entering air cursupport the other; the number of seams and joints can therefore be reduced to a minimum which not only results in a minimum of labor and expense but also reduces the number of seams and rivet joints which are liable to rust out. In the construction shown in Figs. 5v and 6, the cap itself is supported by both the outer cone and the intermediate member. The entire ventilator is preferably constructed of sheet metal, and the in- Loraine termediate Amember can then be formed of a single sheet folded or luted to shape in any suitable manner. In the construction shown in Figs. 5 and 6 this folding maymadein the details of construction without departing from'this invention, and it is therefore to be understood that this invention is not to be limited to the specific construction shown and described. We claimf l. A ventilator comprising an eduction pipe, a casing surrounding said pipe, and means for supporting `said casing in spaced relation with respect to said pipe comprising a plurality of lobes extending along said pipe and lengaging both said pipe and said casing, said lobes being connected to form a substantially continuous element surrounding said pipeand inside of said casing,

whereby a plurality of passages are formed inside of said casingv` and extending along sa-id pipe.

2. Aventilator comprising -an eduction pipe, a easing surrounding said pipe, and

means for supporting said casing in spaced relation with respect to said pipe comprising a plurality of lobes extending along said pipe and engaging bot-h said pipe and said casing, said lobes being formed to extend circumferentially along and in engagement with said casing, said lobes being connected to form a substantially continuous element surrounding said pipe and inside. of 'said casing, wherebya plurality of passages yare formed inside of said casing and extending along said pipe.

3. A ventilator comprisinganeduction 1pipe, a casing surrounding said pipe, means for supporting said casing in spaced relation with respect to said' pipe comprising a pluralityof lobes extending along said pipe and engaging both said pipe and said cas# ing, said lobes being connected to form a substantially continuous element surrounding said pipe and inside of said casing,.

whereby a plurality of passages are formed inside of said casing and extending 'along said pipe, and a cap supported above said pipe and by said casing and saidl lobes.

In testimony whereof we ailix our signatures in presence of two witnesses.
